GOVERNOR FOR WATER-WH EELS.

SPECIFICATION forming part of Letters Patent No. 339,783, dated April 13, 1886.

(No model.)

To all whom it may concern.-

Be it known that I, HENRY E. JAooBs, a citizen of the United States, and a resident of the city and county of Fond du Lac, State of Wisconsim have invented certain new and useful Improvements in Governors for Vater- Wheels, of which the following is a specifica,

tion.

My invention has for its object to secure a uniform movement of a water-motor by the adjustment oi' the inlet gate or valve, and this I effect by connecting an operatingengine with the said gate or valve and by combining a governor driven from the water-motor with the valves of the said engine, as fully set forth hereinafter, and as illustrated in the accompanying drawings, in whichy Figure l is a side View of the actuating-engine, governor, and intermediate parts illustrating my invention. Fig. 2 is an enlarged view illustrating one of the valves.

A represents the cylinder, which contains a piston, B, connected to a piston-rod, C, and the latter is connected through the medium of devices,which need not be shown or particularly described, with the water-gate to be operated, the casing of said gate being indicated by the chest D. It will be obvious, however, that the form of the casing and the character of the gate will vary according to the water wheel or motor which may be employed. The cylinder A is closed at each end, and communicates at one end with the pipe a and at the other with a pipe, b, the said pipes leading, respectively, to valve-casings Il F, each of which also communicates, through a pipe, c, with a pipe, B, leading to any motoriiuid supply-as, for instance, to a water-reservoir, to a reservoir of compressed air, or to a steam-generator, or to a receiver exhausted of air to form a vacuum or partial vacuum in the cylinder-to move the gate-operating pis ton. The stem d of the valve of each of the casings E F is connected to a lever so arranged as to be actuated by a governor, H, of any suitable construction. For instance, the stem d of the valve in the casing E is connected to a lever, G, pivoted between its ends and having at the inner end an opening for the passage of the stem f of the governor, on which stein above the lever G is a lug, s. The stem d of the valve in the case Fis pivoted to a lever, G, having its fulcrum at one end,.the 4other end being perforated for the passage of the stem of the governor and extending above the lug s.

The parts above described are so arranged that the downward movement of the governorstem f will open the valve in the casingEand admit the motor-fluid under pressure, so as to force the piston B to the right and shut the gate, and the upward movement of the gov ernor-stem will open the valve of the casing F, and admit the fluid under pressure to the right-hand end ot' the cylinder A and move back the piston and open the gate, the gate therefore being closed as the speed of the governor increases and opened as the speed decreases.

By connecting the governor so as to be driven in any suitable manner from the waterwheel or the parts moved thereby, the movement of said parts is made the means of regulating the adjustment ot' the gate, and the governor thus maintains a uniform speed. It will of course be evident that lthe valve which controls the flow of the motor-Huid may be of any suitable construction. In Fig. 2 I have illustrated a construction which I have found to be effective. At the bottom of the case E is a raised valve-seat, p, surrounding the entrance-port fr, and to this valve seat is adapted a disk-valve, h, having openings i vertically through it at points outside the part which bears upon the seat, the said disk-valve being secured to the stem d, which is guided by a perforated diaphragm or cross-piece, j. Between the cross-piece j and the valve h is a spiral spring, m, which tends to maintain the valve in contact with its seat, and in the head of the casing E is an opening, e,which is closed by a valve, a, upon the stem d, when the latter is raised and the port a' is opened. The port g/,leading to the pipe a, communicates with the head of the casing below the valve-seat p. Vhen the valve hy is down, the inlet-port x is closed; but when the speed of the governor increases and the stem d is raised with the valve h, the motor-fluid will tlow through the port a' and through the port y into the pipe a and cylinder A, the valve n closing the port e, so that the motor-Huid cannot escape through IOO the latter. Vhen the speed of .the governor decreases and the valve h descends, the port x will be closed; but the water at the left end of the cylinder A can escape through the pipe a, port y, opening 'i in the valve h,and through the port e at the head of the casing.

While I have referred to water as the motorlud, the construction illustrated in Fig. 2 is better adapted for the use of compressed air, as when water is used the parts should be so constructed as to conduct the escaping water away through a suitable tube.

Without limiting myself to the precise construction and arrangement of parts shown, I claim- 1. The combination, with the gate or valve of a water-motor, of an actuating-engine for moving the said gate and two independent casings containing valves controlling the ow of motor-Huid to and from said engine, and a governor connected to operate the said valves,

ernor provided with a stem extending throughy the levers G G. and provided with a lug, a,

between said levers, substantially as set forth.v

3. The combination, with the gate, actuatt ing-engine, governor, and conducting-pipes,

of valve-casings, each provided with a raised valve-seat with ports x, y, and e, with valvesh n, having a common stein, d, with valve h, having perforations outside the valve-seat, and a spring, m, substantially as set forth.
